This transmission gear set is an RC-scale replacement intended for LOSI PROMO-MX motorcycle platforms, supplied as a pair of gears to address worn drivetrain components. The content focuses on fit, function, and the role of the gears in on-track and maintenance contexts rather than specifying dimensions.
Use this set when replacing worn teeth, restoring gear engagement, or when adjusting drivetrain response as part of routine servicing. Install by accessing the motorcycle gearbox area, removing the existing worn gears, and fitting the new gears ensuring proper mesh and clearance with the spur and motor pinion.
Materials and construction aim for consistent engagement under RC loads, and the set serves as a practical spare for riders who perform periodic drivetrain checks or prepare machines for competition runs.
